4 V iJlIlIllJ Patented Nov. 24, 1931 UNITED STATES PATENT; OFFICE WILLIAM H. MUSSEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO PULLMAN CAR AND MANU- FACTURING CORPORATION, OF CHICAGO, ILLINOIS, A. CORPORATION OF ILLINOIS CAR Application filed November 15, 1929. Serial No. 407,459.

The invention relates to metal sash construction designed to permit removal of the glass from the sash without disturbing other elements of the window assembly or removing the sash from the window frame. The invention involves the employment of a metal sash having its essential operating parts, with the exception of certain of the glass retaining strips, all cast in one piece. The invention further contemplates the use of aluminum al- 10y sash in window assemblies as in railway cars and other vehicles where it becomes necessary to reduce the weight of equipment entering into such construction.

It is therefore the principal object of this invention to provide a cast metal sash of simple rugged construction, light in weight, and

adapted for use separately or with another sash in a window assembly.

An important object is to provide side and bottom glass retaining strips of cast metal adapted to serve as weather sealing strips for the sides of the window and formed with a series of lugs designed for interlocking engagement with the sash.

further object is to provide a cast aluminum sash having its metal in the lower rail so disposed as to form a ventilator having portions projecting from opposite sides of the sash and an intermediate air bafile.

The foregoing and other objects are attained by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevational view of an outside sash made in accordance with the invention and showing the glass retaining strips and screen portion of a rail ventilator;

Figures 12 and 13 show in perspective the form of the sockets in the sash and the locking lugs on the glass retaining strips respectively Figure 1 1 is a vertical section therethru on line 1414, of Figure 6; and

Figure 15 is a vertical section through lock pocket in the lower rail of the inner sash showing the latch mechanism retaining late. p In said drawings, 10 represents the window sill of a railway car window, 11 the intermediate sash guides, and 12 the inner sash ing the sash raised, while the outer sash is formed with the intermediate portion of the lower rail 17 bulged to provide a ventilator 18 having an air control grille 19 extending rearwardly from the rear face of the rail and a screen housing 20 projecting outwardly from the opposite or outer face of the sash.

Both outer and inner sash are fitted with removable glass retaining strips 21 and 22 arranged to permit removal or replacement of the glass in the outer sash from outside the car and the glass from the inner sash from the car interior without disturbing either sash or the intermediate screen, or any of the guides. The strips are made to interlock with the respective sash stiles and bottom rails. and held in operative position by screws 23 and 24 placed adjacent the bottom of each sash for convenient manipulation.

For the purpose of providing an effective interlocking engagement between strips and sash, these parts are cast to precise form to insure the accuracy required in assemblies of this character since it is important that the lugs 25 arranged in spaced relation on the strips be entered in sockets 26 of the sash. The present embodiment of the invention utilizes cast aluminum having preferably a silicon content, for silicon expands on freezing and diminishes the contraction of the alloys, to insure the stability of the metal in the sash to prevent objectionable variations in relative alignment of sash or glass retaining strips. The sockets 26 in the sash are formed with contracted end portions 28 flanked by thickened wedge portions 29, as best shown in Figure 12, designed to receive lugs 25 on the strips. As shown in Figure 13, the lugs 25 are formed with inclined wedging underfaces 30 adapted to interlock with and engage wedge portions 28 of the sockets in the sash.

The strips are assembled with the sash by inserting the several lugs thereon within the normal socket openings 26 in the sash and moving the strips and lugs longitudinally until the reduced portions 31 of the lugs enter the contracted ends 28 of the sockets and the wedge portions 28 and 29 become interlocked, whereupon continued movement thereof will draw strip and sash towards each other to clamp the glass 27 between them against vibration and displacement.

As a further guide for the strips during the assembling operation, the strips between the lugs 25 are provided with guide ribs 32 designed to engage corresponding grooves 33 in the sash as shown in Figures 3, 4, and 10, and also to afford a measure of protection against the entrance of foreign matter to the joint about the glass 27. To provide a cushioned bearing for the glass between the strip and sash, the glass is edged with rubber beading 34 of suflicient resiliency to accommodate itself to slight irregularities in the glass, sashand strips, or any of them.

Due to the casting properties of the aluminum silicon alloys employedinmoldingthe sash, it becomes possible to form the sash with a minimum of metal so disposed that suitable recesses and grooves may be provided with their accompaniment of confining walls and flanges as indicated in Figures 3 to 11, inc., to provide seats 35 for the glass, recesses 36 for the sash guide and weather sealing flanges 37 on the posts 13, and marginal stiffening flanges 38, probably best shown in Figures 3. 5, and 10. The upper and lower margins of the sash are preferably of channel section having rebent side flange portions 40 to accommodate resilient supports 39 for the combination weather strip and bumper 41 and the sash sill cushion 42, respectively. As depicted in Figures 3 and 4, the cushion 42 serves to prevent the entry of the elements to the car at the window sill 10, while the bumper and weather strip 41 engages lintel 43 of the window framing to provide a tight closure at the upper end of the sash.

The upper rail of the sash is formed with integral glass retaining strips 44 spaced apart to receive glass 27 with its edge rubber 34, but the lower rail 17 has the separate glass retaining strip 47 of the type indicated for the stile strips '21 and 22 and designed to engage sockets 46 disposed horizontally and spaced transversely of the lower rail.

The lower rail strip is applied after stile strip 21 has been mounted and before the remaining stile strip 22 is placed in position. It will be noted that the sockets 26 in the stiles of'the sash are disposed in the present embodiment with their contracted end portions 28 directed upwardly as shown in Figures 2, 6,and 7, in consequence of which the strips 21 and 22 must be mounted with their respective lugs 25 enteredfirst in the normal openings of the several sockets then pushed upwardly until the sloped undersides 30 of the strip lugs 25 interlock fully with the Wedge portions 29 of the sockets 26 as shown in Figure 14.

For the purpose of locking the strips in their operative positions, suitable plugs 48, preferably knurled to prevent displacement, are embedded in the sash metal during the casting operation and tapped to receive screws 23 and 24 let into the lower ends of strips 21 and 22 as best indicated in Figures 1, 2, 7, 8, and 11. As clearly indicated in Figures 3, (5, and 10, the lugs 25 are disposed with their respective inner edges adjacent shoulder 50 on the sash, the object being that in conjunction with the interengaging ribs and grooves 32 and 33 on strips and sash respectively, the

lugs will engage adjacent shoulders to prevent any tendency on the part of the strips to rock about their longitudinal axes. This feature insures ample clearance in grooves 36 for the sealing flanges 37 on the posts 13 at the outer sash positions and prevents posslble movement of stripsat the stiles to avoid pinching of glass and sealing flanges. A suitable cover strip 45 may be attached to the sash stiles on opposite side of glass retain;

mg strips 21 and 22 to conceal lugs 25 and sockets 26 should that be found desirable. The cover strips may be secured by screws 7 tapped into bosses 8 intermediate sockets 26 on the sash, or otherwise.

1 It will be noted that the lower rail 17 of the outer sash 14 is bulged to form ventilator grille portion 19 on the inner face and screen housing 20 on the outer face of the rail as clearly shown in Figures 1 2, 3, 7, 8, and 9. The ventilator structure is perhaps 7 best illustrated in Figures 3, 7, 8, and 9,

tion as sash lifts as shown in Figures 2, 7,

and 8. The grille is formed with the usual draft openings 53 adapted to be closed by slide 54 having a series of slots 55 spaced to register with the openings in the grille. The slide is actuated by handles 56 formed on the plate which is made preferably of tempered aluminum plate supported in upper and lower guides 57 and 58, respectively, and curved on a larger radius than the face of grille 19 so that its upper and lower edges along their outer faces will bear yieldably against the guides, the intermediate portion of the inner face of the slide contacting with contiguous portions of the grille 19 between draft openings 53 with sufiicient pressure to insure positive engagement between slide and guides. The guides are secured by screws 59 tapped into the sash metal as indicated in Figures 2, 3, and 7'. Suitable stops 49 are provided at the end plates 51 adjoining the sash lifts 52 to limit slide movement at full open or closed stages of the grille.

The screen housing 20 of the ventilator on the outer side of the rail is formed with elongated openings 60 between the end plates 51 adapted to be closed by a fine mesh aluminum screen wire fabric 61 held extended in a metal frame 62 slid endwise into position between upper and lower margins of the elongated openings 60 and within respective adjacent grooves 63 communicating with slots 64 in the end plates 51 for inserting the screen as shown in Figure 3. To prevent endwise displacement of the screen 61 the frame 62 may be bent at its ends or otherwise distorted to lock it in position within the ventilator.

Intermediate the screen housing 20 and control grille 19, and rising from the base of the rail and substantially within the plane of the sash, is a baflie plate portion 65 extending between andconnecting ventilator end plates 51, to diminish the force of incoming air currents by directing them in a circuitous path to the grille 19, and also to prevent the entry of water and probably foreign matter to the car interior as will appear from an inspection of Figure 3, wherein the bafile is shown with its upper marginal portion extending in the general direction of the screen housing 20 and in spaced overlapping relation with the screen openings 60, the baflie at its base having a curved deflecting surface 66 designed to return water reaching the battle to the screen openings to bedrained.

For locking the inner sash in raised or lowered position, the lower rail 70 of the inside sash 15 is formed with a pocket 71 having bearings 72 for supporting a lock spindle 73 having an integral operating thumb piece 16 projecting through opening 74 above sash lift 75 and an integral locking dog 76 depending from the protruding end of the spindle 7 3 for engaging the sash stops 77 on the window frame. By depressing thumb piece 16, the spindle to which it is attached is rotated, causing the dog 76 to be retracted to disengage the sash from the stops 77. The locking mechanism is made accessible from the front face of sash rail 70, the pocket being closed by cover plate 78 removably held by screws 79 tapped into the sash metal, as shown in Figure 15.

It will be noted that there has been provided an aluminum sash for use in railway and other conveyances in which accessibllity for repairs and replacements and saving of space and weight are important considerations. Because of the relatively high tensile strength and desirable casting properites of the aluminum silicon alloy selected for the sash of this invention it has been possible to form the sash and glass retaining elements of this metal with resulting economy in material and maintenance costs.
